We bought a new MPVI 2 from Atec recently for a customer who has a 2018 Trackhawk. With it we purchased 6 credits for tuning the car. When i went to flash the new tune into the ECM it will not sync all of the credits to the vehicle. I have heard all kinds of nightmares with this new interface and that's why I was so reluctant to purchase this new interface. I have not gotten rid of my two MPVI1s but the customer wishes to have his own and this was all that was available. The licensee screen doesn't pop up like it used to so what the hell am I doing wrong, Also the link to support on one of the thread from Bill isn't working.
